I too am not so good at understanding what I am looking at on these but I do believe I recognize the head. Actually, it seems the head is turned to the left, that the torso is in a fetal position and that the right arm is raised up and out to the torso… hmmm… very interesting. There is a circular object below the baby, I wonder what that is.

The baby is in the middle of the picture like the figure 8. The top one is the head as you had determined, but it is facing front. Correct on the right arm. The circular object below the baby’s head is, in fact, the torso. Since it looks more like an alien (*giggle*), the torso is still skeletal and you should be able to distinguish some ribs and part of the spine.
